You could alter the products-query using this filter-hook: wc_zap_mirror_wp_query
You will need some programming skills for that, or someone else to do it for you.

They’ll have to be more specific than that, errors on their end are meaningless to me.

you can hide an entire category if you’d like
or you could modify the products-query as you wish, but that’ll require some dev skills

Have you changed this line:
$hiddenTermId = 123;
To:
$hiddenTermId = 447;
?

@yehuda123456789 please share your mirror-site URL, links, screenshots or any other public information, that’ll help me – help you (firstly, to understand the problem).

@jdembowski He’s not my client and I have no interest of charging anyone for any kind of support related to my plugins, that was the whole point of publishing them here.
That said, I understand what you’re saying and will have another go trying to resolve @yehuda123456789’s issue within this forum.

@jdembowski It just seems too specific to have any interest for all other forum members.

No.

This filter-hook will hide all products that are assigned to this term/category.
It won’t hide the category from the initial category list, that you could do by yourself on the settings page.

Try adding this filter-hook on your theme’s functions.php file:

add_filter('wc_zap_mirror_wp_query', function ($args) {
    $hiddenTermId = 123;
    $args['tax_query'][] = [
        'taxonomy' => 'product_cat',
        'field'    => 'term_id',
        'terms'    => $hiddenTermId,
        'operator' => 'NOT IN'
    ];
    return $args;
});

Replace the hidden term id, with the id of the category you wish to hide.
That’ll hide all products that are assigned to it.

I’m well aware of that, this version isn’t updated.
Contact Pelecard support to get the latest release.

Hopefully, the SVN version will soon be updated as well.

WooCommerce Subscriptions does not support guest checkout, as stated here.

Yes I did.
It looks fine on my end, but then – there’s a lot of products and categories.

Can they be more specific regarding the issue described?
Also, a little bit less technical, like, with the error they attached.

Please share your mirror site address.

Seems like an error thrown from 3rd-party code.
Can’t help you, sorry.
